The correct option is A.
Risk taking has been shown to be affected at a BAL of 0.01.
The full meaning of BAL is blood alchol level. Blood alcohol level refers to the amount of alcohol that is present is a specific quantity of one's blood. As the quantity of alcohol one is taking in increasing the BAL also increases and this affect the way one behave. At the BAL of 0.10, one's ability to think and to judge is severely affected thus making one to become prone to unnecessary risk taking behavior.

The conduction of nerve impulses relies upon the movement of positively-charged ions across the nerve cell membrane. The entry of sodium into the cell produces a wave of positive charge that travels down the length of an axon. Then chemicals called neurotransmitters are secreted out of the end of the axon onto the next nerve in the series (the postsynpatic nerve). This narrow space in between neurons is called the synapse. These neurotransmiiters released by the presynaptic nerve bind to receptors on the postsynaptic nerve. The binding of these receptors opens up channels in this second nerve's membrane that allow sodium ions to enter the nerve cell and initiate another wave of positive charge, and so on... The nerve signal can only move as fast as these ions and neurotransmitters can diffuse to generate this process.
<span>As a professional athlete repeats a given activity many times over, the nerve cells "upregulate" their receptors, meaning that they produce additional receptors to put in the membrane. This is just a natural reaction to the nerve being repeatedly stimulated in the same way over and over. When neurotransmitter is secreted from the presynaptic neuron, there are more receptors on the postsynaptic neuron for it to bind, more channels open up, more ions enter in a shorter time and build up positive charge to create the impulse faster, and so the overall effect is faster. </span>
<span>Additionally, there are sheaths of fatty tissue (called myelin) that insulate the charge in the neuron and allow it to be conducted faster. As people age, these sheaths can start to degrade, making the nerve cell more "leaky" and causing the impulse to be conducted more slowly. </span>

Answer:
C
Explanation:
A)
DNA directs the synthesis of RNA.
B)
DNA splits into two strands of RNA.
C)
A strand of DNA is used as a template for the formation of RNA.
D)
Two strands of RNA are formed by copying each of the strands of DNA.
The correct answer would be that <u>a strand of DNA is used as a template for the formation of RNA.</u>
<em>Transcription is a process during which RNA is synthesized using DNA as a template. The coding strand of the DNA is utilized as a template for the formation of messenger RNA. During this process, the double helix structure of the DNA is unwound by an enzyme and the coding strand is bound by a short DNA strand at the beginning of a gene while another enzyme adds RNA nucleotide bases to elongate the short strand.</em>
The correct option is C.
